Mikanda yoyandama ndi mipira yopanda kanthu yomwe imatha kuyandama pamwamba pa madzi. Ndi yoyera ngati imvi, yopyapyala komanso yopanda kanthu, komanso yopepuka kulemera. Kuchuluka kwake ndi 720kg/m3 (yolemera), 418.8kg/m3 (yopepuka), ndipo kukula kwa tinthu tating'onoting'ono ndi pafupifupi 0.1 mm, pamwamba pake ndi potsekedwa komanso posalala, kutentha kwake kumakhala kochepa, ndipo kukana kwake ndi ≥1610℃. Kapangidwe ka mankhwala ka mikanda yoyandama makamaka ndi silicon dioxide ndi aluminiyamu oxide. Ili ndi makhalidwe ambiri monga tinthu tating'onoting'ono, topanda kanthu, kulemera kwake kopepuka, mphamvu yake yayikulu, kukana kukalamba, kukana kutentha kwambiri, kukana kutentha, kukana kutentha, kukana kukana ndi kukana moto. Imagwiritsidwa ntchito kwambiri mu Chimodzi mwa zipangizo zopangira makina oletsa kukana.
